Emulsions and latexes containing polymer particles with a diameter greater than 0.02 micron are prepared by (i) forming a microemulsion containing particles of oligomers with a diameter less than 0.02 micron by combining water, a surfactant, a hydride functional organosilicon oligomer or a mixture of such oligomers, and an alkenyl functional organosilicon oligomer or a mixture of such oligomers; (ii) adding a catalyst to the microemulsion; (iii) initiating polymerization of the oligomers; and (iv) continuing polymerization until an emulsion or latex is formed containing polymer particles with a diameter greater than 0.02 micron.

Liquid Crystals are thought of as being complex fluids, underpinned by self-assembly and self-organisation within partially ordered fluids, and which sit between solid and liquid states of matter. The realm of the field stretches from low molar mass to polymeric materials, from organic to inorganic substances, and from being functional materials to biological organelles. In this article, we explore
